World Chess Solving Championship

The World Chess Solving Championship (WCSC) is an annual competition in the solving of chess problems organised by the World Federation for Chess Composition (WFCC), previously by FIDE via the Permanent Commission of the FIDE for Chess Compositions (PCCC).

The participants must solve a series of different types of chess problem in a set amount of time. Points are awarded for correct solutions in the least amount of time. The highest score at the end of the competition is proclaimed the winner.

The Tournament consists of six rounds over two days, with three rounds each day according to the following table:

  • Round 1 – 3 twomovers 20 minutes solving time
  • Round 2 – 3 threemovers 60 minutes solving time
  • Round 3 – 3 endgame studies 100 minutes solving time

  • Individual – Likewise, for an official individual world championship to take place, 30 solvers from at least 10 countries must participate. This number too has grown from 18 in 1977 to well over 70 in the past six years (as of 2007).

Rating

Formulas

For calculating ratings for players who previously did not one, a provisional rating is given. This rating is given at the completion of the player's first tournament where the formula used is as follows:

  • Provisional Rating = (Average Tournament Player's Rating) x (Player's Result / Average Result At Tournament)

For players who have previously established a rating the following formula demonstrates how a new rating is achieved.

  • New Rating = (Old Rating) + (KT) x (Player's Result - (Average Result x Old Rating / Average Tournament Old Rating))

KT = Tournament Coefficient (Ranging from 4 to 1 depending on strength of competition)
